Key result
Phosphorylation of Hsp20 at Ser16 by PKA is vital for its cardioprotective actions against myocardial ischaemia/reperfusion injury and apoptosis.
Phosphorylation of Hsp20 at Ser16 by PKA is a critical mechanism for cardioprotection against ischemic injury and apoptosis, representing a potential therapeutic target.

May identify Hsp20 Ser16 phosphorylation as therapeutic target in ischaemia/reperfusion; leaves open clinical translation.
Edwards et al. (2012) conducted a review in Myocardial ischaemia/reperfusion injury and remodelling. Hsp20 phosphorylation at Ser16 by PKA vs. Unphosphorylated Hsp20 or wild-type was evaluated on Cardioprotective effects (myocardial infarct size, recovery of contractile performance, apoptosis). Phosphorylation of Hsp20 at Ser16 by PKA is vital for its cardioprotective actions against myocardial ischaemia/reperfusion injury and apoptosis.
